		<h2>代码示例</h2>

		<code>
		const geometry = new THREE.PlaneGeometry( 2000, 2000 );
		geometry.rotateX( - Math.PI / 2 );

		const material = new THREE.ShadowMaterial();
		material.opacity = 0.2;

		const plane = new THREE.Mesh( geometry, material );
		plane.position.y = -200;
		plane.receiveShadow = true;
		scene.add( plane );
		</code>
